Wonky Idle + Engine Light = O2 Sensor?

Hi - the engine light came on (briefly, then went out) a couple of times this week. The last two days at a coldstart, the idle kind of sputters and chokes a bit, then briefly races to around 2000 then kind of settles back down after I hit the accelerator pedal and put the car in gear and go. the idle then seems ok except i can hear a kind of surging, but it's still around 900. after driving a bit, parking the car, and starting up an hour or so later, everything is normal, with an even idle. is there some kind of system that regulates the cold start process? could it be a lazy O2 Sensor or something else "sticking" somewhere? Normal diving is fine, acceleration fine, performance seems as usual.
thanks for any help!!!
